WILLIAM S. WIT'IN,OF CHICAGO, ILLINOIS.

DUMP-WAGON.

Specication of Letters Patent.

Patented Nov. 12, 1912.

Application filed September 12, 1910. Serial No. 581,683.

To all whom 'it may concern:

Be it known that I, WILLIAM S. WITTEN,

a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Dump -VVagona of which the following is a speciiication, reference being had to the accompanying drawin s.

Ivly invention relates to carts or wagons provided with a tilting bed for discharging the load, and particularly to such vehicles provided with an end-gate which, when the wagon bed is in its normal or operative position, closes the end of the bed and when the bed is tilted to dump the load is arranged to leave the end of the bed f ree and unobstructed for the discharge of its contents.

The present invention embodies some of the broad features of construct-ion and operation described and claimed in my pending applications Ser. No. 483,498, filed March 15, 1909, and Ser. No. 519,361, filed September 24, 1909, and comprises certain improvements in the construction and operation of the wagon as a whole and particularly in the manner of mounting the wagon bed and the end-gate, as will be particularly hereinafter pointed out.

What I regard as new is set forth in the claims.

In the accompanying drawings,-Figure 1 is a side view of my improved wagon J showing the several parts in operative positioii; Fig. 2 is a similar view showing the bed and end-gate in dumping position; Fig. 3 is a plan view of the wagon in the position shown in Fig. 1; Fig. 4 is a rear end view; Fig. 5 is an enlarged detail, being a horizontal section on line 5 5 of Fig. 1; Fig. 6 is an enlarged detail, being a partial section on line 6-6 of Fig. 1; and Fig. 7 is a perspective view showing the mechanism for locking the front end of the bed down upon the ruiming gear.

Referring to the drawings,-8 indicates the wagon bed, which is preferably in the form of a rectangular boX of which 9-10 are the sides, 11 is the front end, and 12 is the bottom. The bed is open at the rear so that by tilting it the load may be discharged at that end, and as best shown in Fig. 2 the rear ends of the sides 910 are curved as shown at 13 so that the upper edges of the sides are shorter than the lower edges. As

will be hereinafter explained, the contour of the rear ends of the sides of the box co-n forms substantially to the arc of a circle of which the pivot of the bed is the center.

14 indicates the rear wheels, 15 the front wheels, and 16 the usual connecting frame, which together make up the ruiming gear and may be of any approved construction.

17 indicates the rear axle.

1118 indicates a bolster mounted on the rear aX e.

19 indicates a pivot which supports the bed upon the bolster 18, said pivot being mounted in brackets 20 provided at the rear upper margin of the holster 18 and having bearings in brackets 21 secured to the sides of the bed, as shown in Fig. By this arrangement the bed may be tilted freely so as to depress its rear end, and when in its normal or horizontal position it rests upon the bolster 18, as shown in Fig. 1. As shown in Figs. 1 and 2, the bolster 18 is provided with a forward extension 22 to provide a more extended support for the bed when in its normal position, and the pivotal connection of the bed is so arranged as regards the longitudinal center of the hed that the bed is supported substantially centrally when in carrying position.

23 indicates a cross-bar, which is secured to and extends across the forward portion of the ruiming gear, as best shown in Figs. 3 and 7.

24 indicates an angular bar secured on the front face of the front of the bed, said bar having an arm 25 which, when the bed is in its normal position, rests upon the bar 23, as shown in Fig. 7. The purpose of this arm 25 is to provide means by which the bedmay be locked down in operative position, this being accomplished by a locking lever 26 which is pivoted at one end to the bar 23, as shown at 27 in Fig. 7, so as to be capable of being swung over and away from the arm 25. The free end of the lever 26 is adapted to move under a clip 28 secured to the bar 23 in convenient position and may be secured thereto by a pin 29 which passes through said clip and into a socket provided in the bar 23 to receive it. By moving the lever 26 into locking position, the front end of the bed may be securely locked to the running gear, and by moving the lever 26 out so as to release the arm 25 the bed may be tilted. For lifting up the front end of the bed to dump the load I provide a lever 30 which is pivoted at its rear end upon the bar 23 so as to be capable of swinging up and down, as shown at 31 in Fig. 2. The front of the bed is provided with a roller 32 carried in brackets 33, said roller being arranged to overlie the lever 30, as shown in Figs. 1 and 3 in such manner that by lifting up the lever 30 upward pressure may be applied to the roller 32, thereby lifting the front end of the bed.

34- indicates yielding supports provided at the rear of the bed for supporting it when in its dumped position.

35 indicates the end-gate which corresponds in width with the bed. At its ends the end-gate is provided with side members 36-37 which register with the sides 9-10 of the bed, their forward faces being curved to conform to the curvature of the rear ends of said sides, as shown in Figs. 1 to 3. The end-gate 35 is supported by side-bars 38-39 which are connected to the side-members 36 37, respectively, at the upper forward portions thereof, as shown at 4-0 in Figs. 1 and 2, the arrangement being such that the lower margin of the end-gate has a tendency to swing forward when the endsgate hangs pendent on its pivots. The forward ends of the bars 38-39 are pivoted to the running gear by pivots Zl1 which are placed at such distance from the pivot 19 of the bed that by the swinging of the bars 38-39 the endgate moves through an are which intersects the rear margins of the sides of the bed, the arrangement being such that when the bed is swung to operative position and the rear ends of the bars 38-39 are swung downward the end-gate will be moved into position to close the end of the bed and at the same time will be clamped tightly against the sides of the bed. In order to automatically operate the bars 38--39 to move the end-gate into or out of operative position when the bed is swung in one direction or the other, said bars extend under guide-straps 4t2-t3 secured to the sides of the bed, as shown in Fig. 6, said straps being provided above and below said bars with anti-friction rollers 4.4.-45 which, by the swinging of the bed, operate to raise or lower the bars 38-39, as the case may be.

t6-t7 indicate tapered locking plates, which are secured to the lower end portions of the end-gate, as shown in Fig. 4, and when the end-gate is in operative position are adapted to tit into sockets formed by adjustable clips 48-49 which are secured to the rear portions of the bed, as best shown in Figs. 4 and 5. As therein shown, it will be seen that the clips 453-49 are provided with nuts 50-51 on the ends thereof, said nuts being'screwed thereupon so as to provide for considerable adjustment of the position of said clips. As also shown therein, the outer ends of each of the clips )f8-t9 are secured in brackets 53 which project laterally from the sides of the bed, but any other suitable arrangement may be employed for the purpose. A.LG-47 tapered, as shown, they have a wedging effect and operate to bind the lower margin of the end-gate more closely against the lower portion of the bed. The lockingplates 46-47 are long enough so that when the end-gate is in its elevated or inoperative position they project over the sides of the bed and operate to guide the lower portion of the end-gate along the sides of the bed and cooperate with the bars 38-39 to keep it from being displaced.

By a comparison of Figs. 1 and 2 it will be apparent that when the bed is in operative position the end-gate will fit closely across the rear end thereof and its side members will be held tightly in contact with the sides of the bed, its lower margin being securely locked in position by the clips 43-49- W hen the front end of the bed is lifted to dump the load, the bed will rock aboutV the pivot 19, carrying its front portion upward and thereby lifting the bars 38-39 through the action of the rollers l5 upon said bars. This will lift the end-gate and will also re lease the locking-plates @t6-47 from the clips iS-49. Further tipping of the bed will cause the several parts to assume the position shown in Fig. 2, lthe lower marginjof the end-gate bearing against the upper edges of the sides of the bed. At this time the lower edge of the end-gate will swing forward under the action of gravity owing to the location of the pivots 40. The lowerend of the end-gate will nevertheless be free to swing backward to permit of the passage of lumps or masses as they slide downward in the bed, so that the discharge of the load is left perfectly free even though it may project a considerable distance above the upper edges of the sides of the bed. When the load has been dumped, the front end of the bed is drawn downward, thus causing the lower margin of the end-gateto slide back along the sides of the bed until it reaches the rear edges thereof and moves down automatically into operative position, this being effected by the action of the rollers 44 upon the upper margins of the bars Btl- 39. The locking-plates 46c-4:7 yautomatically move into the embrace of the clips 48-49 so that when the bed is restored to its horizontal position the end-gate is securely locked in place.

It will be noticed that the action of the end-gate in moving into and out of operative position is positively controlled at all times so that the use of the wagon on hilly or uneven roads or in situations where it is tilted in one direction or another in no wise By making the locking-platesaffects the operations ol' theend-gate, as it y When the bed is tilted to dump the load and is necessarily moved into proper operative position when the bed is restored to its carrying position. By curving the forward edges of the side portions of the end-gate and the rear edges of the sides of the bed in the manner described and supporting the end-gate by bars 38-39 as shown and described, the sides of the bed coperate with the side portions of the end-gate in making a sort of cam-lock Which operates to clamp the end-gate very tightly against the ends of the bed and thereby insures a tight closure ci' the bed at the rear, prevent-ing the escape of its contents.

The improvements herein claimed are not restricted solely to use on Wagons of the type shown and described, as some or all of them may be applied to other forms of Wagons, carts, cars, or other vehicles, and the claims hereinafter made are therefore to be construedV accordingly. Furthermore, my invention, generically considered, is not restricted to vehicles in which the end-gate is located at the rear end of the vehicle bed, but contemplates also the use of equivalent devices that may be employed in beds arranged to dump at other points t-han at the rear. The term end-gate is therefore to be construed accordingly.

That which I claim as my invent-ion, and desire to secure by Letters Patent, is,--

l. A dumping vehicle, comprising suitable running gear, a box mounted thereon and adapted to tilt to discharge its load, an end-gate for said box, bars connected with Vthe running gear and with the end-gate, and

means carried by the box and movable longitudinally of said bars for holding the endgate out of operative position When the box is dumped.

2. A dumping vehicle, comprising suitable running gear, a box mounted thereon and adapted to tilt to discharge its load, an end-gate for said box, bars pivotaliy condiopies cf this patent may be obtained for five cents each, by addressing the Commissianer of Patents.

nected with the running gear independently of the box, and means carried by the box and movable longitudinally of said bars for holding the end-gate out of operative position When the box is dumped.

8. A dumping vehicle, comprising suitable running gear, a box mounted thereon and adapted to tilt to discharge its load, an end-gate for said box, bars connected with the running gear and with the end-gate, and means carried by the box and movable longitudinally of said bars for holding the end gate out of operative position when the box is dumped and for holding the end-gate down in operative position when the box is in operative position.

4. A dumping vehicle, comprising suitable running gear, a box mounted thereon and adapted to tilt to discharge its load, said box having the rear ends of its sides curved, an endgate for said box having side extensions curved to tit the sides cf the box, bars connected with the running gear and with the end-gate, and means carried by the box and movable longitudinally of said bars for holding the end-gate out of operative position when the box is dumped and for holding the end-gate down in operative position when the box is in operative position.

5. A dumping vehicle, comprising suitable running gear, a box mounted thereon and adapted to tilt to discharge its load, bars connected with the running gear, an end-gate suspended from said bars, and means carried by the box and movable longitudinally of said bars for holding the end` gate out of operative position when the box is dumped, the rear ends of the sides of the box being curved and the end-gate having side extensions Which are curved to it the end portions of the sides of the box.
